💖 mipi_dsi_dcs...t_sleep_mode(9) 💖

okay so real talk, this is a Kernel API Manual page, and the function we're stanning today is mipi_dsi_dcs_exit_sleep_mode — the whole entire name got squished in the title but you know her 🫶

---

✨ NAME ✨

mipi_dsi_dcs_exit_sleep_mode — bestie, this is the one that wakes up all the blocks inside the display module like "rise and shine babe" 🌸

---

🦋 SYNOPSIS 🦋

int mipi_dsi_dcs_exit_sleep_mode (struct mipi_dsi_device *dsi );

---

🎀 ARGUMENTS 🎀

• dsi — the DSI peripheral device. that's it, that's the whole argument, she's low maintenance 💅

---

🔥 DESCRIPTION 🔥

okay so here's the tea and I need you to hear me: this function is deprecated. 😭 not in a cancelled way, in a "she did her thing but there's a newer girl" way.

use mipi_dsi_dcs_exit_sleep_mode_multi instead. periodt. ✨

---

🌈 RETURN 🌈

• 0 on success — slay, she ate, no notes 👑
• a negative error code on failure — 💀 not the vibe, go check your errno
